Abstract

Fluvial habitats are inherently variable. They are shaped by flow magnitude, frequency, timing and duration, by the effects of upstream and downstream features along flow paths and by bioclimatic processes and human activities in upstream contributing catchments. Managing freshwater ecosystems requires tools and data that effectively account for these multi-scale processes. We tackle these challenges in this analysis of the distribution of 17 native and alien fish species in south-eastern Australia. A fine-scale, stream-link-based GIS database comprising an extensive set of ecologically meaningful attributes at multiple scales was developed to characterise the multidimensional environmental ..
